We present candidate strong galaxy-galaxy lenses detected in
the Deep Lens Survey (DLS), a ground based weak lensing
survey covering 20 square degrees to R~26. Lens systems are
detected in the DLS using a new method based on the shape
parameters of lensed galaxies (or "arcs"). We simulate the
shapes of possible arcs in the DLS using real galaxies from
deep HST fields as sources. The properties of the arcs are
constrained in a parameter space which includes the third
order (octopole) moments and ellipticity. The shape
parameters of arcs are then combined into a multi-parameter
probability space, from which candidates are selected.
